"As the amount of information in biology expands dramatically, it becomes increasingly important for textbooks to distill the vast amount of scientific knowledge into concise principles and enduring concepts.As with previous editions, Molecular Biology of the Cell, Sixth Edition accomplishes this goal with clear writing and beautiful illustrations. The Sixth Edition has been extensively revised and updated with the latest research in the field of cell biology, and it provides an exceptional framework for teaching and learning.The entire illustration program has been greatly enhanced.Protein structures better illustrate structure?function relationships, icons are simpler and more consistent within and between chapters, and micrographs have been refreshed and updated with newer, clearer, or better images. As a new feature, each chapter now contains intriguing openended questions highlighting ?What We Don?t Know,? introducing students to challenging areas of future research. Updated end-of-chapter problems reflect new research discussed in the text, and these problems have been expanded to all chapters by adding questions on developmental biology, tissues and stem cells, pathogens, and the immune system."

"ABSTRACTLatar belakang: Diagnosis pasti kanker paru ditegakkan dengan menemukan sel ganas pada pemeriksaan sitologi/ histopatologi pada spesimen yang didapat dari berbagai prosedur diagnostik.Tujuan: Untuk mengetahui jumlah sel ganas dari pemeriksaan sitologi yang didapat dari berbagai prosedur diagnostik TTNA terpandu CT scan, TTNA tidak terpandu, TTNA terpandu USG, BJH, sikatan bronkus, bilasan bronkus, TBNA, BAL, sitologi cairan pleura dan sitologi sputum .Metode: Penelitian potong lintang pada slide pasien kanker paru dari pemeriksaan sitologi yang ditegakkan dari berbagai prosedur diagnostik di Rumah Sakit Umum Pusat Persahabatan. Data diambil dari laborarorium Patologi Anatomi, Rekam Medis Rumah Sakit Umum Pusat Persahabatan dan data khusus Adenokarsinoma paru diambil dari laboratorium KalGen Jakarta Pusat pada periode 1 Juni 2015 sampai 31 Juli 2016. Slide pasien yang mengandung sel ganas akan dikoding oleh SpPA dan dihitung jumlahnya dibawah mikroskop dibawah supervisi Sp.PA.Hasil: Sampel penelitian 425 slide sitologi dengan karateristik pasien laki-laki 72,5 median usia 57 tahun, range usia 26-92 tahun dan pasien kanker paru perempuan 27,3 median usia 54 tahun, range usia 18-84 tahun . TTNA terpandu CT Scan merupakan prosedur diagnostik yang paling sering dapat menemukan sel ganas > 200 16,9 , diikuti BJH dengan jumlah sel > 200 11,8 , TTNA tidak terpandu dengan jumlah sel ganas > 200 7,3 . Jumlah sel ganas minimal yang memungkinkan untuk pemeriksaan molekuler lanjutan EGFR khususnya pada jenis adenokarsinoma paru adalah didapatkan 0,8 pemeriksaan EGFR pada jumlah sel ganas < 50 sel dan semakin tinggi jumlah sel ganas maka semakin memungkinkan untuk pemeriksaan molekuler lanjutan. Jumlah slide mempengaruhi jumlah sel ganas yang didapatkan nilai p=0,000 dan semakin banyak jumlah slide maka semakin banyak juga jumlah sel ganas yang didapatkan.Kesimpulan: Jumlah sel ganas pada slide sitologi kanker paru paling banyak ditemukan dengan pemeriksaan TTNA terpandu CT scan, dikuti BJH dan TTNA tidak terpandu. Jumah slide mempengaruhi jumlah sel ganas nilai bermakna, p= 0,000 .Kata kunci: Kanker paru, sel ganas, slide sitologi, prosedur diagnostik

ABSTRACTBackground A definitive diagnosis of lung cancer by finding malignant cells on cytology histopathology examination of the specimen obtained from a variety of diagnostic procedures.Objective To determine the number of malignant cells of cytologic examination that are obtained from a variety of diagnostic procedures CT guided TTNA, unguided TTNA, ultrasound guided TTNA, FNAB, bronchial brushing, bronchial washing, TBNA, BAL, cytology examination of pleural fluid and sputum cytology .Methods A cross sectional study in lung cancer patients slides from cytological examination from a variety of diagnostic procedures in the Central General Hospital Persahabatan. Data are taken from Anatomical Pathology laborarorium, Medical Record of Central General Hospital Persahabatan and the specific data of lung adenocarcinoma taken from the laboratory KalGen in Central Jakarta from1 June, 2015 until July 31, 2016. Slides containing malignant cells of patients are to be coded by SpPA and numbered under a microscope under the supervision of Sp.PA.Results The research sample with characteristic cytologic slide of 425 male patients were 72.5 median age 57 years, range 26 92 years of age and female lung cancer patients were 27.3 median age 54 years, age range 18 84 year . CT guided TTNA was a diagnostic procedure that was most often able to find malignant cells 200 16.9 , followed by the BJH of cell counts 200 11.8 , unguided TTNA with the number of malignant cells 200 7.3 . Minimal number of malignant cells that were possible for advanced molecular examination EGFR , particularly on the type of lung adenocarcinoma was obtained 0.8 EGFR examination in the number of malignant cell "

"Kitosan dan deksametason merupakan material yang digunakan dalam rekayasa jaringan tulang. Kitosan biasa digunakan sebagai scaffold, sedangkan deksametason sering digunakan sebagai sinyal. Salah satu penanda diferensiasi osteoblas adalah Alkaline phosphatase (ALP). Penelitian ini bertujuan menganalisis efek kitosan dibandingkan deksametason dalam menginduksi diferensiasi osteoblas melalui aktivitas ALP pada sel punca pulpa gigi (SPPG). Aktivitas ALP dianalisis dengan ALP assay. Terdapat 4 perlakuan yang memiliki aktivitas ALP diatas kontrol, yakni kitosan 5 ng/ml, deksametason 10 nM dan 100 nM, serta campuran kitosan 5 ng/ml dan deksametason 10 nM. Peningkatan konsentrasi deksametason meningkatkan aktivitas ALP. Peningkatan konsentrasi kitosan menurunkan aktivitas ALP.

Chitosan and dexamethasone are materials that can be used in bone tissue engineering. Chitosan is often used as a scaffold, while dexamethasone is often used as signal. One of the markers of osteoblast differentiation is Alkaline phosphatase (ALP). This research objective is to analyse the effects of chitosan compared to dexamethasone in inducing osteoblast differentiation through ALP activity in Dental Pulp Stem Cells (DPSCs). ALP activity determined by ALP Assay. There were four treatments that have higher activity than the control, they are chitosan 5 ng/ml, 10 nM dexamethasone and 100 nM, and mixture of chitosan 5 ng/ml and 10 nM dexamethasone. The increased concentrations of dexamethasone increases ALP activity and the higher concentration of chitosan will decrease the ALP activity."

"Kitosan telah diketahui sebagai material scaffold poten pada rekayasa jaringan tulang. Penelitian ini bertujuan menganalisis potensi lain kitosan sebagai induktor diferensiasi sel punca pulpa gigi (SPPG) menjadi osteoblas dibandingkan dengan deksametason yang telah umum digunakan, melalui ekspresi mRNA Col1A1. SPPG dikultur pada medium yang mengandung kitosan, deksametason dan kombinasi keduanya selama 7 hari. Ekspresi mRNA Col1A1 diuji dengan metode comparative CT real-time PCR. Medium mineralizing yang ditambahkan 5 ng/ml kitosan dapat meningkatkan ekspresi mRNA Col1A1 pada SPPG dibandingkan dengan kontrol dan kelompok perlakuan lainnya (p<0,05). Kitosan dapat menginduksi diferensiasi tahap awal SPPG menjadi osteoblas bergantung pada konsentrasi yang diberikan.

Chitosan has been proven as potential scaffold in bone tissue engineering. This research intends to analyze the other potency of chitosan as inductor in dental pulp stem cell (DPSC) differentiation into osteoblast compared to dexamethasone which is commonly used, by Col1A1 mRNA expression. DPSC were cultured in medium loaded with chitosan, dexamethasone and combination of both for 7 days. Col1A1 mRNA expression was analyzed by comparative CT method real time PCR. Mineralizing medium loaded with 5 ng/ml chitosan could enhance Col1A1 mRNA expression compared to control and another treated group on p<0,05. Chitosan could stimulate early stage of osteoblast differentiation. The effect was dose-dependent."
